ALDI’S UNBEATEN RUN CONTINUES AS IT IS CROWNED WHICH? CHEAPEST SUPERMARKET FOR MAY 

4 June, 2026

• Consumer champion Which? has named Aldi the UK’s Cheapest Supermarket for May – a 100% record in 2026 which extends back to November 2025 

• Shoppers can save a total of £67.19 by switching from Waitrose to Aldi 

New analysis from consumer champion Which? has once again confirmed Aldi as the UK’s cheapest supermarket for May 2026, based on a basket of 95 popular grocery items.   

Even after loyalty discounts were applied, shoppers would still have paid up to £30 less at Aldi than at Sainsbury’s (priced £198.79) and Tesco (£196.88). Morrisons was £29.20 steeper (£197.50), while Waitrose was a whopping £67.19 more than Aldi for the same basket at £235.49. 

The result continues Aldi’s strong start to 2026, having topped the Which? rankings every month so far this year and building on its recognition as Cheapest Supermarket of the Year for 2025¹.  

The retailer was also recently named Which?’s ‘Best Value Brand of the Year’, recognised for consistently delivering strong quality at low prices².  

Julie Ashfield, Chief Commercial Officer at Aldi UK, said: “Being named the UK’s cheapest supermarket once again by Which? is fantastic recognition of our unwavering commitment to offering customers the very best value. At Aldi, we know how important it is for shoppers to make their money go further, especially as we head into the summer months. Our low prices mean shoppers can enjoy great quality food without overspending.”
